Rust Type System Overload

Send UnwindSafe<T> Arc<T> Borrow<T> DerefMut Deref Sync Drop UnsafeCell<T> PhantomData<T> Unpin Clone Rc<T> ToOwned Copy Sized Cow<'a, b> where B: 'a + ToOwned + ?Sized &T] Weak<T> Box<T> AsRef<T> Pin<P> BorrowMut<T> Ref<'b, T> Cell<T> RefCell<T> RefMut<'b, T>

A crying, overloaded humanoid is surrounded by Rust traits and smart-pointer types such as Arc, Rc, RefCell, Cow, and Box. The joke is that Rust’s ownership, borrowing, lifetime, and concurrency concepts feel overwhelming to beginners. People send it as a reaction when Rust code or compiler errors become incomprehensible.
